GENERAL DESCRIPTION 

Butterfly-Sentinel (B-sentinel in the following) is a multiparametric wireless sensor for the continuous forest monitoring and the alarm management in case of fire. B-Sentinel is able to transmit data via GPRS in a protected internet area (FTP area) and to send alarms in real time via SMS to alert the available personnel quickly.  The climatic parameters which are the macro-descriptors of a forest fire and that are monitored by Butterfly-F, are typically the temperature and humidity of the air and the carbon dioxide (CO2); Furthermore B-Sentinel is very versatile because it can connect several kind of transducers for the environmental and industrial  monitoring, making it extremely adaptable to any remote measuring application.

WORKING LOGIC

B-Sentinel has an operating logic managed by a microprocessor that allows you to configure both the data storage and transmission rate and the alarm thresholds of all connected measurements.

Each individual B-Sentinel independently acquires the instantaneous data of the connected sensors and verifies that the CO2 value is lower than the set threshold value (the value is always checked every 5 minutes to allow the CO2 sensor to preheat):

1) If the value is below the threshold, B-Sentinel remains silent and stores the data without activating the alarm. In this mode, B-Sentinel periodically sends a simple confirmation of its functionality to the server.

2) If the value is above the set threshold, the system activates by sending two alarm SMS to two available people and at the same time begins to transfer the new information to the dedicated web server
